2014 Mercedes-Benz E 2.1L Diesel · BT14 AAF

A recurring corrosion issue on the off‑side front brake pipe dominates the MOT record, appearing as an advisory on three consecutive tests (December 2025, December 2025 retest and July 2026). The most recent inspection confirmed the vehicle passed, but the same pipe was again noted as corroded and covered in grease, indicating that the problem has neither been resolved nor escalated to a failure. Apart from this, the MOT history shows a single failure in December 2025 driven by multiple tyre defects and a rear position lamp fault, after which the car has returned to a clean‑pass status with only advisory items. At 127,077 mi over twelve years the average annual accumulation is roughly 10,600 mi, which sits comfortably within typical usage for a 2014 Mercedes‑Benz E‑Class. MOTs have been recorded at regular twelve‑month intervals with no significant gaps, suggesting the mileage figure is reliable and that the vehicle has not experienced periods of prolonged inactivity. This level of use will have naturally advanced wear on consumables such as tyres, brake pads and discs, while the moderate mileage reduces the likelihood of premature major power‑train failure, provided the wear items are addressed. Prospective buyers should give particular attention to the off‑side front brake pipe: inspect visually for rust, pitting or any signs of fluid leakage, and feel for a soft or spongy pedal during a test drive. The advisory on rear brake pads wearing thin and the front disc being pitted but not seriously weakened also merit close examination; listen for any pedal pulsation, especially under moderate braking, and check the disc surface for deep scoring that could affect braking efficiency. Because the December 2025 failure highlighted severe tyre damage—a bulge on the off‑side front tyre, exposed ply on the near‑side rear tyre and tread below 1.6 mm—ensure that all four tyres are replaced with a matched set, and verify that sidewalls are free of bulges or separations before committing to purchase. Additional advisories concerning rear brake‑pipe condition, fluctuating front service brake and a deteriorating rear registration plate should be reviewed but are unlikely to pose immediate safety concerns if the brakes feel firm and the plate remains legible. The near‑side rear position lamp fault recorded in 2022 should be confirmed as operational, as a non‑functioning lamp can lead to a re‑test. Overall, the vehicle’s roadworthiness hinges on resolving the brake‑pipe corrosion, confirming the integrity of the braking system, and fitting a fresh set of tyres to eliminate the previous dangerous tyre defects.
